Two years later....

The client wants to add a panasonic cordless to the phone system. The cordless has lines 1 and 2 only. The client has line 1 as the main line and line 2 as the fax line. The gate is on co3 in intercom mode on the panasonic system. Am I correct that the cordless will not be able to answer the gate because it only has two lines and the system is in intercom mode and the gate line is in effect "line 3"?

Thanks!
